Three alleged gangmembers beat and robbed a woman in South San Francisco Tuesday afternoon, according to police.

Nicholas William Rodriguez, 18, of South San Francisco, Eric Esqueda-Perez, 21, of South San Francisco, and an unnamed juvenile were arrested after attacking a 46-year-old woman.

The woman was walking southbound on the 800 block of Hickory Place around 3:25 p.m. when she felt someone come up behind her and pull on her purse, South San Francisco police said.

The woman tried to hold on but was punched in the face multiple times by one of the men, according to police.

The woman sustained injuries to her face, chest and back and was transported to the hospital.

The three suspects were arrested and appeared in court Thursday afternoon on felony charges of robbery for gang purposes and the commission of a gang crime. Each asked for court-appointed attorneys and pleaded not guilty to the charges. They did not waive their right to a speedy trial and return to court July 16 for a preliminary hearing.

Bail was set at $100,000 for each and they remain in custody.

Esqueda-Perez also has a no-bail hold for allegedly violating his felony probation with the new arrest. In March, Perez was sentenced to 90 days jail and three years probation for selling marijuana the previous December.
